First date! What do I wear!?!?

It's a childhood friend I've taken interest in, so he knows me well, but I LOOOVE dressing up. I don't know just what to wear though. Here I am: http://a3.sphotos.ak.fbcdn.net/hphotos-ak-snc6/190467_1608747183851_1391341995_31351529_5416225_n.jpg What do I wear? How do I do my hair (I like pigtails)? We're going to the movies if that helps, Insidious. LOL!
